Abstract: An optical scan module, for example for an optical scanner, includes an integrally molded plastics material member which defines not only the laser focusing lens, but also the laser focusing aperture and the collection mirror. In addition, the molded member may act to house and to locate both a semiconductor laser and a photodetector, thereby ensuring easy and accurate placement of those elements within the scanning assembly. The optical assembly may be in modular form, mounted onto a common printed circuit board with a beam scanner.

Abstract: LASER SCANNING SYSTEM COMPACT BAR CODE SCANNING MODULE WITH SHOCK PROTECTION Optical scanning of barcode symbols is carried out first in an aim mode wherein the symbol is scanned using a first scan pattern that is relatively small and dense so as to be visible to the user, and thereafter using a second, larger, more robust scan pattern for decoding. The preferred scanner module has a scanner mirror which is mounted to a bracket by way of a leaf spring, allowing the mirror to oscillate in one direction. This is hung from a stationary chassis by means of two strips of mylar film, which are themselves protected against mechanical shock by pins which pass through holes in the bracket. The pins provide accurate alignment of the bracket with respect to the chassis.

Abstract: A data transfer system for an LCD price tagging arrangement includes an electro-optical scanner and one or more LCD price tags. Each LCD price tag is associated with a given product in a retail outlet and carries price or other information relating to that product. The LCD price tag includes an electro-optical detector for detecting a beam generated by the scanner. The scanner light beam generating source is modulated such that the beam carries product information. Accordingly the price or other product information on the LCD price tag can be quickly and efficiently updated.

Abstract: A first module (10), including a laser for emitting a laser beam and a photodiode for detecting light reflected from a bar code symbol, is independently mounted on a support (14a) in a spaced relation to a second module (12) which includes a movable reflector and a drive for moving the reflector. The reflector is advantageously mounted for oscillation on a pair of taut elements constituting an endless band.

Abstract: An optical scanning system for reading indicia of differing light reflectivity has an optical scan module which is adapted to be mounted on a finger of a user. A first peripheral module, preferably in the form of a wrist watch, has a receiver which detects the reflected light. A second peripheral module, mounted on the other arm of the user, communicates with the first module by radio frequency transmission. According to other aspects of the invention, the light detector may be mounted in a housing which is separate and apart from the optical scan module. According to another aspect, a laser pointer or scanner is mounted to a ring which is arranged to be worn on a single finger of the user.

Abstract: A compact assembly for electro-optically scanning indicia includes an oscillatable component operative for focusing, and for sweeping, a light beam across the indicia and, optionally, for correcting for scan aberration. A laser diode for emitting the beam is inserted into a central opening surrounded by an electromagnetic coil to conserve space. A magnet on the component interacts with the coil to effect oscillation. A floating flexure returns the component to an equilibrium position.

Abstract: An optical scanning module has orthogonally-mounted first and second circuit boards (416,418) which carry circuitry that operates together to produce the signals necessary for operation of the module, and to process electrical signals from a reflected light detector. In a preferred embodiment, scanning of the light beam is achieved by reflecting the beam from a mirror (159) which is mounted to a support (103) which itself is mounted for reciprocal oscillation on leaf springs (121,123). Oscillation is provided by the interaction of a permanent magnet (109) on the support (103), and a stationary electro-magnet (133). The invention also encompasses systems for scanning the beam simultaneously in two orthogonal directions, and for producing a moving zig-zag scanning pattern.

Abstract: A bar code reader has an integrated scanning component module which is mountable on a printed circuit board. In one embodiment, the module may include the digitizer/decoder electronics, enabling the module to be used with a generic PCB. In some embodiments, the module includes a high speed optical scanning arrangement having an optical element which extends longitudinally of a flexible member, secured at one end. In other embodiments, the invention extends to a hand-held optical scanner having a scanning assembly, detector and data transmission coupling all mounted to a common printed circuit board, preferably located within a manually-graspable handle. In yet a further embodiment, an abuse-detector or accelerometer is provided for determining when the device is exposed to deceleration above a predetermined limit, and optionally for automatically shutting down applications programs and for providing a black-box-record of a short time frame before the device was exposed to an unexpected shock. Preferably, the reader is shock protected by a thermo-plastic elastomer housing section. An outgoing light beam is directed at a non-orthogonal angle relative to the PCB.
